PCT/US2015/065022
USE OF ANTI-VEGF AGENTS TO TREAT LESIONS IN
MACULAR DEGENERATION PATIENTS
Age related macular degeneration (AMD) is a medical condition that usually
affects older adults and
results in a loss of vision in the center of the visual field (the macula)
because of damage to the retina.
It occurs in "dry" and "wet" forms. In the dry form, cellular debris called
drusen accumulates between
the retina and the choroid, and the retina can become detached. In the wet
form (wAMD), which is
more severe, blood vessels grow up from the choroid behind the retina which is
also named choroidal
neovascularization (CNV). As a result of CNV the retina can also become
detached.
The proliferation of abnormal blood vessels in the retina is stimulated by
vascular endothelial growth
factor (VEGF). Antiangiogenics or anti-VEGF agents can cause regression of the
abnormal blood
vessels and improve vision when administered intravitreally. Several anti-VEGF
drugs have been
approved for use in the eye and are described in the following patent
applications:
Aflibercept (Eylee) W02000/75319
Bevacizumab (Avastin 0) WO 9845331
Ranibizurnab (Lucentie) W09845331
Pegaptanib (Macugen ) W09818480
KH-902/conbercept (Langmu ) W02007112675
Besides anti-VEGF treatment wAMD can be also treated with photodynamic therapy
with
Verteporfln (V -PDT), whereby closure of leakage is induced by laser light in
combination with
visudyne, an i.v. injectable photosensitizer.
Clinical trials performed with anti-VEGF agents required the inclusion of
patients with an active
predominantly classic, subfoveal CNVarea that must occupy at least 50% of the
total lesion
[Rosenfeld et al. N Engl J Med 2006, 355:1419-1431; Brown et al. N Engl J Med
2006, 355:1432-
1444; Heier et al. Ophthalmology 2012, 119:2537-2548; Regal et at. Am J
Ophthalmol 2008,
145:239-248]. Hence there is a dearth of information regarding the response of
eyes with an active
predominantly classic, subfoveal CNVarea that occupies less than 50% of the
total lesion to anti-
VEGF therapy.
The CATT research group compared the baseline characteristics, treatment
frequency, visual acuity
(VA), and morphologic outcomes of eyes with >50% of the lesion composed of
blood (B50 group)
versus all other eyes (Other group) enrolled in the Comparison of Age-Related
Macular Degeneration
Treatments Trials (CATT). Treatment for the study eye was assigned randomly to
either ranibizumab
or bevacizumab and to 3 different dosing regimens over a 2-year period.
Reading center graders
evaluated baseline and follow-up morphology in color fundus photographs,
fluorescein angiography

(FA), and optical coherence tomography (OCT). Increases in mean visual acuity
(VA) were similar in
the "B50 group" and the "Other group" at 1 year (+9.3 vs +7.2 letters; P =
0.22) and at 2 years (9.0 vs
6.1 letters; P = 0.17). Mean lesion size in the "B50 group" decreased by 1.2
DA at both 1 and 2 years
(primarily owing to resolution of hemorrhage) and increased in the "Other
group" by 0.33 DA at 1
year and 0.91 DA at 2 years (P < 0.001). The authors concluded that the "B50
group" had a visual
prognosis similar to the "Other group". Lesion size decreased markedly through
2 years. Eyes like
those enrolled in CA-1'1' with neovascular AMD lesions composed of >50% blood
can be managed
similarly to those with less or no blood. [Mtaweel MM et al. Ophthalmology.
2015 122(2):391-398].
However, the above evaluated subpopulation with >50% of the lesion composed of
blood is not equal
to the subpopulation of patients with active CNV lesion < 50% of the total
lesion size of the study
described in this application (example 1).
According to the invention there are two subtypes of wAMD: (I) small active
CNV lesion ¨ type of
wAMD or (11) predominantly active CNV lesion ¨ type of wAMD. The location of
the lesion can be
subfoveal or juxtafoveal affecting the fovea. The type of the lesion can be of
all subtypes including
predominantly classic, minimally classic, or occult.
The terminology for the two types of wAMD is preliminary. Alternate terms for
the "small active
CNV lesion ¨ type of wAMD" may include:
1) "sCNV wAMD"
2) "wAMD with small active CNV"
3) "wAMD with reduced active CNV"
4) "wAMD with less CNV"
5) "Non-CNV related wAMD"
6) "wAMD Type 1"
7) "wAMD Type 2"
8) "wAMD Type X", where X is any number, letter or combination of both.
In the under 1 ¨ 8 listed alternative terms for "reduced active CNV ¨ type of
wAMD"
alternative terms for "wAMD" can be:
a. "wet AMD"
b. "neo vascular AMD"
c. "nAMD"
d. "exudative AMD"
e. "eAMD"
Alternate terms for the "predominantly active CNV lesion ¨ type of wAMD" may
include:
2

CA 02970315 2017-06-08
WO 2016/094673 PCT/US2015/065022
1) "pCNV wAMD"
2) "wAMD with predominant active CNV"
3) "wAMD with active CNV"
4) "wAMD with large active CNV"
5) "CNV related wAMD"
6) "wAMD Type 1"
7) "wAMD Type 2"
8) "wAMD Type X", where X is any number, letter or combination of both.
In the under 1 ¨ 8 listed alternative terms for "reduced active CNV ¨ type of
wAMD"
alternative terms for "wAMD" can he
a. "wet AMD"
b. "ncovascular AMD"
c. "nAMD"
d. "exudative AMD"
e. "eAMD"
In the following, the terms "sCNV wAMD" and "pCNV wAMD" will be used.
While the presence of active CNV lesion and thereby the diagnosis of wAMD is
usually confirmed by
fluorescence angiography (FA), the two wAMD types can be differentiated as
follows:
1) "sCNV wAMD" is characterized by an active CNV lesion that occupies less
than 50% of the
total lesion size
2) "pCNV wAMD" is characterized by an active CNV lesion that occupies at least
50% of the
total lesion size.
The location of the lesion can be subfo veal or juxtafoveal affecting the
fovea. The type of
the lesion can be of all subtypes including predominantly classic, minimally
classic or
occult.
The size of the active CNV lesion as well as the total lesion size is
determined using Fluorescence
Angiography (FA) as described in the MPS protocol [Macular Photocoagulation
Study Group, Arch
Ophthalmol 1991, 109:1242-1257].
With the invention, it is shown that lesions with small active portion of the
CNV lesion (<50% of total
lesion size; "sCNV wAMD") respond well to treatment with anti-VEGF treatment,
namely aflibercept,
or PDT. This conclusion is based on an observation made in a clinical trial
with patients with "sCNV
wAMD" and "pCNV wAMD" which were treated either with intravitreal injection of
aflibercept or
V -PDT. Surprisingly, the response determined by visual acuity of the "sCNV
wAMD" patients to the
aflibercept treatment was numerically higher to the response of the "pCNV
wAMD" patients. This
3

CA 02970315 2017-06-08
WO 2016/094673 PCT/US2015/065022
was not expected because it is assumed that lesions with a large active
portion of the CNV lesion arc
more receptive to the anti-leakage effect of the anti-VEGF treatment than
lesions with small active
portion of the CNV lesion. In addition, the response to the V -PDT treatment
of the "sCNV wAMD"
patients is numerically higher to the response of the "pCNV wAMD" patients,
which was not expected
as well.
According to the invention, treatments for wAMD can be also used for the
treatment of patients with
"sCNV wAMD". Such treatment of patients with "sCNV wAMD" may be as follows:
1) Intravitreal anti-VEGF monotherapy similar to the treatment of wAMD,
whereas anti-VEGF
therapy refers to all approved and non-approved treatments aiming to attenuate
free VEGF in the
eye. This includes particularly aflibercept, ranibizumab, bevacizumab, KH-902,
and pegaptanib,
but is not limited to these compounds. Anti-VEGF treatment may be applied
according to the
following treatment schedules:
a. Three monthly intravitreal injections or three intravitrcal injections each
4 weeks apart
followed by dosing every other month or every 4 weeks with or without the
option to
extend the treatment interval further during the later treatment phase.
b. Treatment until visual acuity and/or retinal morphology (e.g. as assessed
by OCT.
Fluoresceine Angiography, Inclocyanine Angiography, Funduscopy, etc.)
stabilizes,
followed by discontinuation of treatment. Re-initiation of treatment upon
deterioration of
visual acuity and/or retinal morphology.
c. Any as needed (pro-re-nata ¨ "PRINT) regimen
d. Any Treat&Extend regimen
e. Any other treatment regimen that is or has been used for treatment of
wAMD
2) Therapy with one or more of the following treatments. If more than one
treatment is used, they
may be used at the same time or sequentially.
a. Anti-VEGF treatment as described under 1)
b. Single or repeated applications of photodynamie therapy with
Visudyne (V -PDT)
c. Single or repeated applications of steroids (all available local
or systemic application
routes) including slow-release or depot formulations (e.g. Ozurdex,
triamcinolone,
dexamethasone, Iluvien, etc.)
d. Radiation therapy
e. Thermal laser therapy including sub-threshold treatments
f. Surgical therapy
g. Pharmacological vitreolysis (e.g. with Jetria or other approved or non-
approved drugs)
h. Systemically or locally applied inhibitors of tyrosine kinases
i. Systemically or locally applied inhibitors of the VEGF receptor

Example 1:
A total of 304 Chinese subjects with age-related neovascular or wet age-
related macular degeneration
were enrolled in a randomized, double-blind clinical study to assess the
efficacy of intravitreal (IVT)
administrated aflibercept compared with V'-PDT on the mean change in BCVA
(Best corrected visual
acuity) from baseline to Week 28. BCVA of the study eye was assessed according
to the standard
procedures developed for the ETDRS (Early Treatment Diabetic Retinopathy
Study) adapted for Age
Related Eye Disease Study (AREDS). The key inclusion criteria were as follows:
= Signed and dated written ICE
= Men and women L.50 years of age.
= Active predominantly classic, subfoveal choroidal neovascularization (CNV)
lesions
secondary to AMD, including juxtafoveal lesions that affect the fovea, as
evidenced by
fluorescein angiography (FA), in the study eye.
and
= ETDRS best corrected visual acuity (BCVA) of 73 to 25 letters in the
study eye (Snellen
activity equivalent of 20/40 to 20/320 in the study eye).
The following key exclusion criteria applied for the study eye:
= Total lesion size is greater than 12 disc areas (30.5 min2, including
blood, scars and
neovascularization), as assessed by FA
= Sub-retinal hemorrhages that is >50% of the total lesion area, or if the
blood is under the fovea
and is 1 or more disc areas in size. (If the blood is under the fovea, then
the fovea must be
surrounded by 270 degrees by visible CNV.)
= Presence of CNV with an origin other than wAMD. History or clinical
evidence of diabetic
retinopathy, diabetic macular edema or any retinal vascular disease other than
wAMD.
Particular attention should be made to exclude subjects with polypoidal
choroidal
vasculopathy (PCV).
= Presence of scar, fibrosis, or atrophy involving the center of the fovea
that indicates
substantial irreversible vision loss.
= Presence of retinal pigment epithelial tears or rips involving the
macula.
Eligible patients were randomized 3:1 to receive aflibercept (VTE) 2Q8 or V -
PDT (228 VTE+76
PDT). 194 patients with active CNV lesions >= 50% (147 VTE2Q8 4 47 PDT) and
106 patients with
active CNV lesions < 50% (78 VTE2Q8 + 28 PDT) were included. The lesion size
was determined by
a central reading center based on the MPS protocol [Macular Photocoagulation
Study Group, Arch
Ophthalmol 1991, 109:1242-1257]. The active CNV size, the area of CNV (nun2)
as well as the total
lesion size was measured using the FA. The central retinal thickness was
determined by optical
coherence tomography. In the VTE2Q8 group patients were treated with 2 mg
(0.05 mL) aflibercept

administered intravitrcally at baseline, week 4, 8, 16, 24, 32, 40 and 48. In
the PDT group V -PDT
was performed at baseline and potential PDT retreatment according to the
guidelines for the use of
PDT treatment in wAMD [Verteporfin Roundtable Participants, Retina. 2005;
25(2):119-34] were
performed at week 12 and 24. At Week 28, after assessment of the primary and
secondary endpoints,
subjects in the PDT-,-VEGF Trap-Eye group received an IVT injection of 2.0 mg
VEGF Trap-Eye,
followed by additional 2.0 mg VEGF Trap-Eye injections at Weeks 32, 36, 40,
and 48.
Intravitreal injections of 2 mg aflibercept was superior to V -PDT with a mean
change from baseline
BCVA fetter score at week 28 of 14.0 (-29 to 59) VTE2Q8 group versus 3.9 (-36
to 43) PDT group
(P<0.0001) in the whole study population irrespective of the active CNV lesion
size. Intravitreal
injection of 2 mg aflibercept provided an effective treatment for patients
with an active CNV lesion <
50% of total lesion size (mean change of BCVA from baseline at week 28: 16.7 (-
21 to 59) see figure
2/2) which was comparable to the treatment outcome of patients with an active
CNV lesion >. 50% of
total lesion site (mean change of BCVA from baseline at week 28;12.7 (-29 to
40) see figure 1/2). V _
PDT treatment effect is numerically higher in patients with an active CNV
lesion <50% of total lesion
size (mean change of BCVA from baseline at week 28: 8.0 (-18 to 43), see
figure 2/2) than in patients
with an active CNV lesion >= 50% of total lesion size (mean change of BCVA
from baseline at week
28: 1.5 (-36 to 27) see figure 1/2).
In general, for most of the other efficacy parameters a more favorable outcome
in patients with an
active CNV lesion <50% of the total lesion size compared to those with an
active CNV lesion >=50%
of the total lesion size was observed for patients both treated with VTE2Q8
and V -PDT (table 1).
